“Roadrunner’s revenge,” wrote Wilson as he posted the video on Instagram. “This big bird bully chased me on my bike near the Cotter today, and I wasn’t the only one. I’d like to see Wile E Coyote take on this brute. That’s not a roadrunner, this is a roadrunner!”

Wilson was wise to give the bird some distance. Emus, a native species of Australia, can grow to just under two metres tall, and can reach speeds of up to 48kmh (30mph) and weigh between 36-40kg.

Like any other animal, emus can be protective of their territory, particularly during the breeding season.
